SPECIFICATION farming pm of Letters Patent No. 701,801, dated .Iene-s, 1902. Application tiled December 26,1901. Serial No. 87,260. (No model.)

To n/ZZ whom it may concern/r Be it -known that I, KARL ,'DEINLEIN, a subject of the Emperor of Austria-Hungary, re#- siding at Iilsen,'in the Province of Bohemia, in the Empire of AustriafHungary, have invented certain new and useful Improvements in Recoil Apparatus for Ordnance; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled 4in the art to which it appertains to make and use the same, reference bein ghad to the accompanyingdrawin gs, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improved means, in combination with a recoil-brake for ordnance provided with recoil-carriages, for returning a ,gun to its firing position, and comprises apparatus, hereinafter referred to as compoundreturn apparatus, adapted to be inserted as a single article into the top earriage of the gun or to be removed therefrom when it may be desired to change it. This compound return apparatus comprises substantially two or more coiled springs arranged between telescopic tubes, the outermost tube` being adapted to slide in the top carriage and v being connected to the piston-rod of the brake, while the innermost tube is adapted to slide on the brake-cylinder. The ends of the telescopic tubes are closed by stationary and movable annular parts, as presently described, thatserve asv abutments for the ends -of the springs. Theindividnal tubes are prevented from sliding away from one another or from the brake-cylinder under the pressure of the springs inserted between them by means of rings screwed either to the fixed annular parts or to the brake-cylinder.

vReturn apparatus according tol this invention may thus-form one vcompound article and can be inserted in the top carriage with the springs extended and be secured in positionby means of the screwed ringthat connects it to the brake-cylinder, and, if desired, the return apparatus can be changed a's one compound article after removing the screwed ring.

1During the backward movement of the gun the coiled vspring having the largest diameter. is compressed by means ofthe outermosttube simultaneously with the movement of the brake-piston until the compression of the said .I' spring overcomes the resistance of the spring next in order, and this lsecond. spring is in turn compressed by the telescopic tube that surrounds it, which is moved forward by the'l outermost spring, and so on, the power required .for returning the gun to the tiring position being thus stored up in the springs.

One example of ,compound return apparatus according tothis invention and having two springs is illustrated in the accompanyv v ing drawings, in which- Figure 1 shows a side elevation of thegu'n and a part longitudinal section th rough the top carriage, thebrake-cylinder and the springs beinglin thepositions they respectively oc cupy before firing. vation of the gun and the compound return apparatus located in the top carriage shown in longitudinal section, all the parts being in the positions they respectively occupy after the gun has moved back. Fig. 3 is a crosssection of Fig. 1; and Fig. 4, a section, drawn to a larger scale, showingthe forward and rear ends, respectively, of the compound return apparatus.

. ou is the brake-cylinder, which is attached to the top carriage b at its forward endandin which there is arranged to slide a piston fm provided, as well understood, with holes or Fig. 2 shows a side e1e passages for the purpose of allowing ow of' 'the retardiu g liquid and whose rod Zpasses outannular part abuts` against the'ring d, screwed to the brake-cylinder. in its extended position by means of the shoul- 'surrounding the brake-cylinder, and the said.

The spring f is held` der formed on the forward end of the inner tube e, that surrounds tliespring. The tube e is also provided vat its rear end with a shoulder, against which the spring f2, that surrounds the tube e, bears. This second spring is surrounded by the outer tube g, connected to the gun h, and bears, as does also a shoulder formed on the forward end of the tube g,

against an annular part It', adapted to'slide ou the tube e and to keep the extended springr f2 in position.

At the rear end of the tube g there is fixed a cover,to which the rod Z of the brake-piston is secured.

In order, o n the one hand, to prevent the annular parts c and 7c from beingr forced outward under the pressure of the ext-ended springs j" and f when the compound return apparatus is not secured to the brake-cylinder, and, on the other band, to maintain the springs in an extended condition, there are screwed behind the annular parts c and k into the correspondingrends of the tube c rings o and 2;, so as to enablea compound return apparatus to be withdrawn from or placed in the top carriage as one article. For this purpose itis only necessary in the one case to unserew the rin,y (Zfrom the brake-cylinder or in the alternative case to screw on the ring after a fresh apparatus has been placed thereon.

During the recoil of the gun 7b the tube g and also the brake-piston rml move in the top carriage b correspondingly therewith. The springjfis compressed by the annular part lr', which is guided on and moves on the tube c. \Vhen its compression is greater than the resistance of the springf, the spring f2 causes the tube c to slide, so that it is moved, together with the screwed rings o andy), in relation to the brake-cylinder (t, and the annular portion c, held by means of the screwed ring (l, and so compresses the spring/'C lhc power required for returning the gun to the Ji ringposition is therefore stored up by means of this telescopicmovement of the tubes g and e ,and the compression ot the springs thereby produced.

I claimma l l. In au apparatus for returning a gun to its Firing position, the combination with a top carriage provided with a slot in the top there of, of a brake-cylinder mounted within and connected to one end of said carriage, a piston arranged in the cylinder, an inner tube .surrounding the brake-cylinder, a spring interposed between said inner tube and said brake-cylinderand adapted to be compressed vby :f id inner tube, an outer'tube inclosing, said inner tube, a springinterposed between the said inner and outer tubes and adapted to be compressed by said outer tube, connections between the outer tube and the gun, and connections between the outer tube and the piston, the compressing of the spring upon the inner tube being` in advance of the compressing of the spring' upon the cylinder during the action of firing.

2. In an apparatus for returning a `gun te 'its normal position, the combination with a top carriage provided with a longitndinaiy slot, of a brakecylinder arranged within said carriage and connected to one end thereof, an inner tube inclosing said cylinder,'a spring interposed `between said inner tube and said cylinder and abutting a shoulder on the lat ter and adapted to be compressed by said inner tube, an Youter tube inclosing said inner tube, a springinterposed between said inner and said outer tube and abutting againstV a shoulder on the-inner tube and adapted to be, compressed by the outer tube, and conu nections between said outer tube and the gnu.

3. In an apparatus for returning a gun te its iii-ing position, the combination with tbe top carriage provided with a longitudinallyextending slot in the top thereof, of a bralze-- cylinder mounted Within and connected to one end of said carriage, a piston arranged in the cylinder, an innertube surrounding the brake-cylinder and having at its forward end an internal shoulder and at its rear end an external shoulder, an aunulus interposed between ythe rear end of the tube andsaid cylinder, a ring` d secured to the cylinder and arranged vbetween the same and said annulus, a ring o secured to said tube and interposed between 'the same and said ring d, a spring surrounding.,y said cylinder and abutting against the internal shoulder of" the inner tube and said annulus, an outer tube inelosing said inner tube and provided with an internal shoulder at its forward end, an annulns inu terposed between said outer and. inner tube and abutting against the internal shoulc'er of the outer tube, a ring@ secured to the inner ytube and arranged between the saine and said outer tube, a spring mounted `upon said inner tube and abutting against said annulus and external shoulder of the inner tube, connections between said outer tube and the gun, and connections between said outer tube and the piston.

mln testimony that I claim the foregoing as niy invention I have signed my naine in prcsence of two subscribing witnesses.
